My invention relates to a control valve for containers.

The object of my invention is to provide a spring actuated valve.

1 6 A further object of my invention is to provide a valve mechanism with a locking means for the closed position thereof. 1

A still further obj ectof my invention is to provide a valve mechanism with a concavo- 1 convex element that will seat regardless of the rock of the stem carrying the same.

A still further object of my invention is to provide a simple and eflicient means whereby a. valve for a container may be operated with one hand to open and close the valve and simultaneously manipulate the container that is collapsible.

A still further object of my invention is to provide a valve mechanism that may be attached to the stopper of a bottle and carried 1 thereby.

A still further objectof my invention is 1 to provide a. valve that will automatically close when the contents are compressed by collapsing a flexible container. 1

Theseand other objects will hereinafter be more fully explained, reference being had to the accompanying drawing forming a part of this specification, and in which like characters will apply to like parts in the diflerent views, and in which 1 Fig. 1 is aplan view of afiexible tube. Fig. 2 is a side view partly in section. Fig. 3 is a transverse view of Fig. 2 showing the engagement of the locking means.

Fig. 4 is a similar view to Fig. 3 showing the locking means disengaged and the valve open.

My inventionherein disclosed is the combination of a container 1 having a valve seat 2 at the base ofthe neck 3 integral with the container, the said neckhaving a cap 4 as closing means for the top thereof.

Positioned in the side of the neck is an aperture 5 thru which the contents of the con- .tainer will eject when the valve (later described) is opened.

Note that the type of container I have chosen to illustrate. my invention is a coly lapsible lead tube and may be filled at the bottom portion A after which the sides are pressed together and rolled fluid tight. 1 do not wishhowever, to confine my invention tothis style of container alone asmy valve mechanism may bearranged with and carried by stopper of other style of containers such as bottles, cans, jars,or the like that are non-collapsible, the contents of which are preferably fluid andis equally controlled as that of the paste likesubstance that is commonly placed in alead tube like container. y 1

My valve mechanism consists of a stem 6 1 having a concavo convex valve 7 secured to the inner end thereof and adapted to snugly engage with the said seat 2 regardless of a possible slightrocking movement of the outer portion of the stennshould theaperture 8 be enlarged by any reason in excess of the diameter of the stem slidably engaging therein. 1 1

On the outer end of the stem is secured eccentrically a disc like element 9 on which to place the thumb or finger to move the stem longitudinally for 1 disengagement of the valve, and when released the same is retracted to engagement thru the medium of a spring 10 coiled around the stemengaging be tween the disc and the cap of the stem, and to seal the aperture against possible leakage 1 thereto, I have placed a flexible fibrous 7 washer 11 apertured to snuglyengage on the stem and being tensioned to engagement with the cap by the said spring seating thereon.

Positioned in parallelism with the stem and upwardly extending from the leap and supported thereby is a pin 12 on which the said disc will engage when rocked to registry therewith as shown in Figs. land 3, by which means'the valve member 7 is locked in a closed position. 1 1

The opposite sides from a diametrical line of disc 9 areturned upward as shown in Figs. 3 and 4 to function as a cam to surmount the upper 'endof pin 12 as the discis rocked from either side as shown by dotted lines CC on 1 the axis of the stem, and when rocked from engagement as shown by dotted lines D, the disc is free to move downward as previously described as opening means for the valve.

Such other modifications than previously mentioned may be employed as lie within the scope of the appended claims, and havlng fully described my invention, what I claim as new and desire to secure by Letters Patent 1. In a control valve for containers, in combination with a container having a neck thru which the contents thereof are dispensed, a valve seat at the inner portion of the neck and an apertured cap on the outer end thereof, the neck having a discharge aperture extending thru the side as an exit therefrom, a stem having a disc-like element eccentrically po- 'sitioned on the outer end and a concavo-convex valve engaged on the other end of the stem to engage in the seat, the stem to slidingly engage in the aperture of the cap, a flexible fibrous washer to seat on the cap and thrn which the stem extends, a coil spring wound around the outer portion of the stem to engage between the disc and the washer as tensioning means to seat the valve, and a post positioned on the cap, and on which the disc may be rocked to engagement as locking means for the valve seated.

2. In a control valve for containers of the class described comprising a stem, a camshaped disc eccentrically attached to one end of the stem, a concavo-convex valve secured to the other end of the stem, a container having a discharge in the side of the neck with an apertured cap on the outer end, and a valve seat at the inner end, the stem rotatably carried in the apertured portion of the cap and carrying the disc and valve in its rotation, a spring wound on the stem between the disc and the cap and flexible means to pack the aperture against leakage, means to engage the cam disc to avoid longitudinal movement of the stem inward.

3. In a control valve for containers of the class described comprising a convex valve, a stem and a cam member, the cam secured to i one end of the stem and the valve'to the other,

a container having a discharge aperture in the side of the neck with a valve seat at the inner end and an apertured capsecured'to the outer end, the stem engaging in the last said aperture slidable longitudinally and rotatable, the

valve carried by the stem in working relation to the seat, a pin carried by the cap in working relation to the cam as locking means for a closed position of the valve, and a spring wound on the stem between the cam and the cap as retracting means for the stern when the said stem and cam are'turned from engagement with the pin and moved toward the container all as and for the purpose specified. In testimony whereof I aflix my signature.
